How could some outsider solve problems that thousands of scientists have been working on for decades?
The key word here is ‘decades’. The foundational problems in physics are so old and deeply entrenched, and the theoretical physics community so resistant to change, that the most likely source of the next physics revolution lies entirely outside of this environment. The mystery isn’t how an original solution might come from an outsider; the mystery is why it has taken so long. It goes without saying that skepticism is a valuable attribute, and is, after all, what prompted Terence Witt to pursue the road less traveled. But skepticism should always be tempered with curiosity.
